Baseball Cards Price

How do I go about finding the value of some Topps baseball trading cards from 1978, 1979 about 150 of them.?

How can I find out if any of these Topps chewing gum baseball cards are of value, or if there are just junk that I can sell at a garage sale. All the baseball cards are from 1978, 1979. Need some assistance in this area...

1. if you're lucky ebay
2. Beckett's puts out an annual isssue which values card from difft years. It use to run about $5. Any good magazine or book shop should have it. Or a collector store. I have the complete set from 1970.
